While Spain’s population has increased slightly since the year 2000, the share of the rural and urban populations has remained relatively constant, with Spain being a highly urban country. This consistently high urbanization is a consequence of both economic and social factors. The Spanish wealth is generated in the cities to a large extent Two thirds of Spain’s economic output, as divided across economic sectors, comes from the service sector, with only three percent originating from agriculture. Naturally, service-based economies are easiest when people live closely, while agricultural practices need more land, and thus a rural population. Of course, this also brings economic costs, such as the high living and housing costs in Madrid. What draws people into cities? Social factors also drive people to cities. For some, it is being closer to family or culture, such as art museums. For others, it is finding a large city with green spaces, like Madrid. For others, it is the opportunity to watch a game in a world-class soccer stadium, perhaps FC Barcelona. These and other factors continue to keep Spaniards in their cities.
